IMPROVEMENT IN STOCK-FEED BOILERS.

Specification forming part of Letters Patent No. 201,668, dated March 26, 1878; application filed February 9, 1878.

To all whom it may concern:

Be it known that I, CLINTON R, HARDY, of Lexington, in the county of Scott and State of Indiana, have invented certain Improvements in Stock-Feed Boilers, of which the following is a specification:

As its title indicates, this invention relates to boilers or tanks in which to cook corn, meal, and other food for stock; the object vbeing to provide a cheap and convenient method of heating the water in'the tank or "essel.

The invention consists in the combination, with a U-shaped furnace, of a feed-water-inlet pipe arranged to pass through the said furnace and its chimney, and back into the containing-vessel in which the furnace is 'submerged, all as will be hereinafter set forth.

The figure in the drawing represents, in perspective, my improved boiler, a part of the tank and furnace-flue being broken away to show the interior.

A is a tank or vessel, which may be of wood; and B is a Ushaped furnace and flue, which may be of galvanized iron. Both ends of the furnace open out of the vessel at a b, as shown, and may be connected with the end of the vessel A by means of a,flange-plate, O. The open end a of the flueyserves as the furnace proper, and the fuel is inserted here. The openin g may be closed by a door, D, if desired. The end 11 connects with a chimney, E, whereby the smoke is carried away.

It will be seen that when a fire is kindled in the open end a of the furnace, the flame and products of conibustion, accelerated by the draft, pass through the entire length of the flue and out at the chimney E, thus heatin g the flue in its transit. As the said flue is kept always below the water-line the heat will all be utilized. v

F is a pipe from the pump orwater-supply, arranged to feed water to the vessel A. This pipe enters the top of the chimney E, passes down the same, and through the entire length of the furnace-flue, out at a, and then entersthe vessel at c, and passes back to the rear end. Thus the water is heated before it escapes into the vessel.

The chimney E may be the ordinary stovepipe, and F may be of gas-pipe. Gis a valve to regulate the influx of water.

This boiler is adapted for use on the farm where stock is to be fed, and wood, corn-cobs, cornstalks, or other refuse may be used as fuel in it.

I am aware that agricultural boilers have 7 been constructed in which a continuous returnflue submerged in the fluid contents of the containing-vessel has been used, and I make no claim to this feature; but

What do claim is-- The combination of the vessel A, the U- shaped furnace and flue B, arranged therein as shown, the chimney E, forming aprolongation upward of one extremity of the furnaceflue, and the pipe F entering the chimney at the top, as shown, passing thence down the same entirely through the furnace and flue B, out at the mouth a, and back into the vessel A below the water-line,as and for the pun poses set forth. I

In witness whereof I have hereunto signed my name in the presence of two subscribing I witnesses.
